Some of us feel that the sex scenes were faked and TA was actually being tortured in the bedroom. Someone suggested that the photos of him nude on the bed with an anguished expression on his face were not the countenance of a person interested in voluntarily posing for a fun sex play photo, rather a man under duress. Here are some of the points in favor of this theory:
*There is duct tape on his arm. It is not a Body Bug as some suggested (an exercise aid) because strands of duct tape was identified at the crime scene. Tying a person up via the upper arms was done on another murder I saw on Mystery Detectives--the older guy who went into the desert with a young Wiccan woman and didn't live another day. This method of tieup is also used in SM because it leaves the hands free while impeding aggressive movement.
*The angle of the photos is deliberate because it is bad photography. Both shots do not show his left arm, which could be tied to a foot of the bed.
*JA referred to a rope loop as a "noose"--a very odd choice of words.
*TA appears to be giving a hand gesture in one photo but a WS poster pointed out that he is tossing the KY tube that JA planted, almost in a defiant gesture. The KY tube and his hand are both blurred.
*TA is not the least aroused. It may be a post coital photo since his genital area is reddened, or he could have been sexually assaulted.
*TA's foot shows two rope burns. Either he was tied up in the bedroom or he was dragged by the foot.
I've saved the best evidence for last. The crime scene experts indicated the blood in the bedroom varied in age. There was "old" blood and fresher blood.
In my mind, I think she used the unusual tie-up to sit on him and inflict minor stab wounds because by then, he had refused to be blackmailed (by the photos) and by her threats to tell the bishop he was a pedophile. The evidence of blunt force trauma on his lower limbs has never been explained. I believe she inflicted wounds to him in the bedroom before the shower.
Another theory that explains Travis' weakened condition is that she may have stabbed him in the heart first and he may not have realized the severity of the injury. Many people do not realize they are dying because they feel ok at first. They think they survived because they don't see too much blood. Medical testimony indicates that it would have taken three or four minutes to weaken.
Evidence towards this scenario would be the unnatural position of his hands on his chest on one of the shower photos, the strange poses, the appearance of desperation/pain and general sadness. His basic defiance towards her intimidation might make him not want to show her his pain. WHen he saw the gun, he knew he had to act.
I am sure I have left some things out, but these are some of the ideas that have been floated here.
